I am trying to retrieve a response from my server which ultimately redirects to a URL after post data is submitted. I figured I could retrieve the url response that the server redirects with , with the code below but every time I do i get a fatal error out of memory. I was wondering what may cause this error if any one had any ideas of why I am getting this error or if this is an incorrect way? I have tested I am sending the data correctly to the server but keep getting this error. here is my code.
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://example.com/");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("token", token));
nameValuePairs.add(new BasicNameValuePair("key", "test"));
nameValuePairs.add(new BasicNameValuePair("mac", "test"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
ResponseHandler<String> responseHandler=new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
Log.d("URL", responseBody);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

I am new to android and I have a question about name value pairs that I am a little confused on. For example I am trying to post to the following example and get the response code using the endpoint:
/account/create/bank-id?ssn=SSN&name=NAME&email=EMAIL. I would edit the need to edit the following : bank-id , SSN , NAME, and EMAIL. at the moment. I am thinking along the lines of(so far no luck , no repsponse code are printing so I dont know what I am doing wrong at the moment, ty for any replies):
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://xx.xxx.xxx/account/create/");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("bank-id", "12345"));
nameValuePairs.add(new BasicNameValuePair("ssn", "451"));
nameValuePairs.add(new BasicNameValuePair("name", "kitty"));
nameValuePairs.add(new BasicNameValuePair("name", "kitty"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
Log.d("Http Post Response:", response.toString());
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block

Hi i am trying to connect to Salesforce with the Rest API and i want to retrieve sObjects..Implementing as below
void getsObjects() throws IOException {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://na14.salesforce.com/services/data/v24.0/sobjects");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("X-HostCommonName", "ap1.salesforce.com"));
nameValuePairs.add(new BasicNameValuePair("X-PrettyPrint", "1"));
nameValuePairs.add(new BasicNameValuePair("Host", "ap1.salesforce.com"));
nameValuePairs.add(new BasicNameValuePair("X-Target-URI", "https://ap1.salesforce.com"));
nameValuePairs.add(new BasicNameValuePair("Content-Type", "application/json"));
nameValuePairs.add(new BasicNameValuePair("Connection", "Keep-Alive"));
nameValuePairs.add(new BasicNameValuePair("Authorization", "00D90000000qUEp!AQQAQNnuPZqEX2oqAkeQLmvq.qsBfKIMa3GCJvE7atLv2Cjy94YZn5ezRH0bosXTFthnoMNt.WpDturXB1Ijxxxxxxxxxx"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
httppost.setHeader("Content-Type","application/json");
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
String result = EntityUtils.toString(response.getEntity());
System.out.println("Final response"+result);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
even if i am passing the the Authorization key , it is giving INVALID SESSION error
12-11 14:50:18.108: W/DefaultRequestDirector(27014): Authentication error: Unable to respond to any of these challenges: {token=WWW-Authenticate: Token}
12-11 14:50:18.498: I/System.out(27014): Final response[{"errorCode":"INVALID_SESSION_ID","message":"Session expired or invalid"}]
I am trying to connect to it from 2 days but no luck, can someone point me right direction, how to make rest calls.
The Authorization header should take the form Authorization: Bearer {sessionId} whereas you have Authorization:{sessionId}
You nameValuePairs appears to contains http headers, but you're not creating headers, you're passing them to setEntity, which sets the http body payload, not the headers.
You're creating a bunch of standard headers (like Host) which don't align with the actual url, and these aren't needed anyway.
try something like
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://na14.salesforce.com/services/data/v24.0/sobjects");
httpPost.setHeader("Authorization" , "Bearer " + sessionId)
StringEntity entity = new StringEntity("someJson", "UTF-8");
entity.setCotnentType("application/json");
httpPost.setEntity(entity)
HttpResponse response = httpclient.execute(httppost);
String result = EntityUtils.toString(response.getEntity());
System.out.println("Final response"+result);
You might also want to checkout the Force.com Android SDK which has a bunch of helpers for accessing the API.
I have a backend for my android app, which returns 404 on GET and json on POST. Now, I'm trying to do POST request using this snippet:
public void postData() {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.yoursite.com/api/login");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("email", "email#email.com"));
nameValuePairs.add(new BasicNameValuePair("password", "qwerty"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
Server however receives GET request. With curl POST backend returns json as expected. But somehow httpPost sends GET(!) request. What could be the problem? What am I doing wrong?
Ok guys, answered my own question pretty quickly, may be helpful for others.
I replaced hostname with ip address, and it worked!
I am attempting to help a student write an android app that will contact a specific webserver. From the looks of the website, you can issue a GET requestion with your web browser and you get back a cookie session and an "authenticity token" (see the source of the page as an invisible input)
We issue a GET request and then want to follow it up with the post, but we are receiving a status code of 404 on the post. On a side note, the first GET request returns a code of 200.
Does anyone have any ideas? Below is the code that gets executed...
public void run()
{
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("https://co22.herokuapp.com/login/");
HttpPost httpPost = new HttpPost("https://co22.herokuapp.com/login/sessions");
HttpResponse response;
try
{
response = httpClient.execute(httpGet);
Log.d("matt",response.getStatusLine().toString());
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
nameValuePairs.add(new BasicNameValuePair("session[network_id]", username));
nameValuePairs.add(new BasicNameValuePair("session[password]", password));
nameValuePairs.add(new BasicNameValuePair("authenticity_token","9yvxPOUpRFdsTeHAZtISEfBHpElDTHzvMjAbQnxOHDM="));
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
response = httpClient.execute(httpPost);
Log.d("matt",response.getStatusLine().toString());
}
catch (ClientProtocolException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
It appears that the above will work correctly, but we were just sending the second post request to the wrong website.
I'm currently trying to send data via POST to a server, and the server is handling the data and appends it to a JSON file. I'm currently getting a 422 error and I've been receiving it for a while now. My question is: How do I receive that JSON error itself in Java so that I can see what the error is. All I'm seeing is a HttpResponseException and it doesn't give me anything else. Thanks for the time and help in advance.
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(mPath);
// Add your data
try
{
List nameValuePairs = new ArrayList(4);
httppost.setHeader("Authorization", Base64.encodeToString(new StringBuilder(bundleId).append(":").append(apiKey).toString().getBytes("UTF-8"), Base64.URL_SAFE|Base64.NO_WRAP));
nameValuePairs.add(new BasicNameValuePair("state", "CA"));
nameValuePairs.add(new BasicNameValuePair("city", "AndDev is Cool!"));
nameValuePairs.add(new BasicNameValuePair("body", "dsads is assrawstjljalsdfljasldflkasjdfjasldjflasjdflkjaslfggddsfgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfdsgfddjflaskjdfkasjdlfkjasldfkjalskdjfajasldfkasdlfjasljdflajsdfjasdjflaskjdflaksjdfljasldfkjasljdflajsasdlfkjasldfkjlas!"));
nameValuePairs.add(new BasicNameValuePair("title", "dsaghhhe fd!"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
//HttpResponse response = httpclient.execute(httppost);
//int status = response.getStatusLine().getStatusCode();
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
Log.v(TAG, "response: " + responseBody);
//JSONObject response = new JSONObject(responseBody);
int f = 0;
}
catch(HttpResponseException e)
{
Log.e(TAG, e.getLocalizedMessage());
Log.e(TAG, e.getMessage());
e.printStackTrace();
}
you may send your parameters more conveniently by using predefined Json class as below:
String jsonParam = null;
try{
JSONObject param = new JSONObject();
param.put("state", "CA");
param.put("city", "AndDev is Cool!");
//and so on with other parameters
jsonParam = param.toString();
}
catch (Exception e) {
// TODO: handle exception
}
and set the post entity as:
if(jsonParam != null)
httppost.setEntity(new StringEntity(jsonParam, HTTP.UTF_8));
422 error says: Unprocessable Entity - The request was well-formed but was unable to be followed due to semantic errors
You got a problem with UrlEncodedFormEntity
